Restore DB using SMO without DATABASE is in use error

Question

I am using SMO to restore the database ,

 ServerConnection con = new ServerConnection(_serverName, _userName, _password);
 Server server = new Server(con);
 Restore destination = new Restore();
 destination.Action = RestoreActionType.Database;
 destination.Database = _databaseName;
 BackupDeviceItem deviceItem = new BackupDeviceItem(path, DeviceType.File);
 destination.Devices.Add(deviceItem);
 destination.ReplaceDatabase = true;
 destination.NoRecovery = true;
 destination.SqlRestore(server);

I am getting an exception message :

Exclusive access could not be obtained because the database is in use. RESTORE DATABASE is terminating abnormally.

Answer 1

I resolved the issue by killing the connected processes and database

ServerConnection con = new ServerConnection(_serverName, _userName, _password);
Server server = new Server(con);
Restore destination = new Restore();
destination.Action = RestoreActionType.Database;
destination.Database = _databaseName;
BackupDeviceItem deviceItem = new BackupDeviceItem(path, DeviceType.File);
destination.Devices.Add(deviceItem);
destination.ReplaceDatabase = true;
destination.NoRecovery = true;
server.KillAllProcesses("your db name");
server.KillDatabase("your db name");
destination.SqlRestore(server);
